1. Select the Backpack: Choose a sturdy, weather-resistant backpack that can accommodate the solar panel securely.

2. Prepare Solar Panel: Install a foldable solar panel on the outside of the backpack, securing it with straps or Velcro.

3. Connect to Battery Pack: Wire the solar panel to the battery pack, ensuring a clear pathway for the energy transfer using a USB charging circuit.

4. Mount Circuit: Place the circuit inside the bag’s compartment to protect it from weather elements.

5. Test Connections: Bring everything together and test the output. Make sure your devices can charge via the USB ports.

6. Secure and Finalize: Ensure all cables are tied down and secured to prevent movement during hikes.

Usage Tips:

• Perfect for long hikes or travel, allowing you to charge multiple devices on the go.
• Keep your backpack facing the sun as much as possible during rest breaks for continuous charging.

5. Solar Water Heater Charger

Materials Needed:

• Solar water heater kit (miniature version)
• Small pump
• Battery or water heater with USB output
• Insulated container
• Hoses
• Wiring and connectors
